Revert "mali: GPU OC/UV"

This reverts commit 814a3c9dbc915fd968caeaeedd81dcf2bfd24cf9.
mali: GPU clock and voltage control including auto-applied full freq. range voltage table (Yank555.lu)

- Fixed a derp in mali_platform_dvfs.c that impeeded voltage being initialized for highest frequency (Yank555.lu)

    mali_dvfs_table_update gets called before the initialization of the ASV level, which
    at that stage is reported as ASV 0 when it is 6 once boot is completed on my device

- Included proper voltage table for all 20 freq. levels with automatic update when changing any GPU freq. (Yank555.lu)

SysFS interface :

 * clock control (old legacy interface) :
 *
 *    - set frequencies (5 steps) :
 *
 *          echo "step0 step1 step2 step3 step4" > /sys/class/misc/gpu_clock_control/gpu_control
 *
 *      available frequency steps :
 *
 *           54,  108,  160,  200*, 266,  275, 300,
 *          333,  350,  400*, 440,  500*, 533, 600*,
 *          640*, 666*, 700*, 733*, 750*, 800
 *          (* newly introduced steps)
 *
 *      NB: Any change will trigger a reset of all voltages !
 *
 *    - set frequency-step thresholds (up & down) :
 *
 *          echo "step0_up% step1_down% step1_up% step2_down% step2_up% step3_down% step3_up% step4_down%" > /sys/class/misc/gpu_clock_control/gpu_control
 *
 *      available thresholds :
 *
 *          0% - 100%
 *
 *    - set staycount for each step (default = 0) :
 *
 *          echo "step0 step1 step2 step3 step4" > /sys/class/misc/gpu_clock_control/gpu_staycount
 *
 *      available staycount values :
 *
 *          0 - 255
 *
 * clock control (new interface) :
 *
 *    - set frequencies (5 steps) :
 *
 *          echo "freq" > /sys/class/misc/gpu_clock_control/gpu_freq_0...4
 *
 *      available frequency steps :
 *
 *           54,  108,  160,  200*, 266,  275, 300,
 *          333,  350,  400*, 440,  500*, 533, 600*,
 *          640*, 666*, 700*, 733*, 750*, 800
 *          (* newly introduced steps)
 *
 *      NB: Only actually existing steps will be accepted (old legacy accepts anything between min and max !!)
 *          Any change will trigger a reset of all voltages !
